Marine Weather and Tide Forecast for Trinidad, TX

SHORT TERM
(Today and tonight)
Issued at 115 AM CDT Wed Jul 22 2026

Expect excessively hot and humid conditions today across much of North and Central Texas as a strong upper-level ridge remains planted across the Central and Southern Plains. A weak backdoor cold front is expected to push westward across the region this afternoon and evening, eventually shifting winds out of the east- northeast later in the day. Unfortunately, most will not observe any real temperature drop today, outside of our northeastern counties where afternoon highs will peak around 99-101. Elsewhere, expect temperatures around 100-105 this afternoon. Persistent humidity will keep afternoon heat indices a bit above ambient temperatures, ranging generally between 105-115 degrees. The current Heat Advisory and Extreme Heat Warning remain unchanged for this afternoon.

Outside of the heat, a few CAMs continue to show spotty development late this afternoon into the evening across portions of North and Central Texas. The coverage seems a bit too widespread in the models when taking into account the subsident airmass and the lack of a source of strong ascent. However, I would not be surprised to see a couple of elevated convective attempts near and along the front with the heat and moisture in place. In all honesty, there is a very good chance that the entire region stays dry, but went ahead and added a 10% chance of isolated thunderstorm development for much of Central Texas into western North Texas today to account for the low chance.

Continued east to northeast winds tomorrow will allow for a slight dip in afternoon high temperatures, ranging from the mid 90s to around 102. Like days previous, the heat impacts will really stem from higher heat indices. Much of the area outside of the Red River and far northeast will observe peak heat index values up to 105-106 degrees on Thursday, and have issued a Heat Advisory for that.

LONG TERM
(Thursday through Tuesday)
Issued at 115 AM CDT Wed Jul 22 2026

While the majority of impacts from what is currently Tropical Storm Bertha will remain to our south as head into the weekend, guidance continues to spread some of the tropical moisture up into our Central and Eastern Texas counties Friday onward. This may bring in some increased cloud cover to the southern portions of the region, keeping temperatures in the mid 90s to around 101 this weekend. Further north across much of North Texas, highs will begin to increase once again into the 100-105 degree range this weekend into early next week. With no drier air filtering in, expect humidity to push afternoon heat index values to between 100-108 each day through the rest of the forecast period.
Additional Heat Advisories will likely be needed in the coming days, but this will be decided on each day as we go. Remember to keep cool and hydrated, and to avoid excess time outdoors during the heat of the day.

AVIATION
(12Z TAFS)
Issued at 518 AM CDT Wed Jul 22 2026

Light southwesterly (occasionally variable) winds will prevail over the next hour or two before settling out of the north near 12-13Z, with speeds around 5 kt or less. Expect winds to veer a bit more out of the northeast around 9-11 kt this afternoon as a backdoor cold front pushes through the region. Some CAMs continue to promote spotty showers and storms late this afternoon near and west of the airports, but there is still uncertainty concerning both the coverage and location of this development. As such, will continue to keep the forecast dry for now, and monitor throughout today. If storms are able to develop this afternoon, the most likely timing would be between 22-01Z. Otherwise, expect northeasterly winds to prevail the rest of the period.
